The role of the periosteum in the healing of the dogs muller-plate treated femur fracture

There area cotradictory opinions of the role of the periosteum in the conditions of stable osteosthesis. One group of authors and othere believe that the periosteum, especially its cambian layer, has one of the most important roles int the healing of fractures. However, other group of authors and others deny the crucial role of the periosteum in the healing of fractures. The authors of the present study performed osteosynthesis by the Muller plate in both femoral bones of 20 dogs. In the left femoral bone, the periosteum was removed 4 cm in the proximal and distal direction from the fracture site, while in the right femoral bone the periosteum reamined intact. The healin of th fracture was controlled by X-ray every 15 days up to 2.5 months when the animals were subjected to euthanasia. After 2.5 months from the introduction of the fracture, the healing of the fracture line was recorded in both femoral bones. It is concluded that in the conditions of stable osteosynthesis the periosteum does not play a crucial role in the healing of bones.
